Get the extension SUN with Locker Protocol Wallet
SUN is a DeFi platform on Tron for swapping, staking and providing liquidity.
Use SUN with a wallet whose private key never touches your computer: the site connects to the extension, and every signature is approved on a separate offline device.
Checked against the live site on 2026-09-17
We run the extension against the real SUN site, not a copy of it. On 2026-09-17, all five checks passed:
- 1SUN lists the wallet in its connect menu, under "TronLink".
- 2Refusing the connection leaves SUN idle and grants it nothing.
- 3Approving it walks every window and signature SUN asks for and reaches the working app.
- 4Reloading the page keeps the session without asking for a new approval.
- 5Disconnecting SUN from the wallet's list of connected sites makes the page let go.
How to connect SUN
Install the extension and the Vault
Add Locker Protocol Wallet to Chrome or Brave, and set up the free Locker Vault on a spare phone that stays offline.
Choose "TronLink"
Open SUN, press its connect button and pick "TronLink" in the list, then approve the connection in the extension.
Sign on the offline device
When SUN asks for a signature, the extension shows a QR code. Scan it with the Vault, read the transaction there, approve it, and scan the answer back.
On Tron, the recipient, the amount, the token, the fee limit and the permission are shown before you sign.
SUN and Locker: questions people ask
Is it safe to use SUN with Locker Protocol Wallet?
The wallet cannot make any site safe, but it changes what an attacker can do: the key never touches the computer, every transaction is shown on the offline device before you approve it, and risky approvals and known phishing sites are flagged first.
Which button do I pick on SUN?
"TronLink". That is the entry SUN showed for the wallet when we checked it on 2026-09-17. Sites change their menus, so if it has moved, look for Locker Protocol Wallet or the generic browser wallet entry.
Do I need a hardware wallet to use SUN this way?
No. The key lives on the Locker Vault, a free app you install on a spare phone and keep offline. Transactions travel to it and back as QR codes, with no cable and no Bluetooth.
Does Locker Protocol Wallet add a fee on SUN?
No. Using SUN through the wallet costs only what SUN and the network charge. The wallet's own fee applies to swaps and bridges made from the extension itself (at most 0.25%), shown before you sign.
